So you have installed IBM QRadar SIEM and trying to verify its aliveness using ping command but you realized that ping icmp requests are&nbsp;being dropped? Well, this happens because by default QRadar SIEM drops all ICMP traffic received on the management interfaces.<\/p>\n\n\n\n<div class=\"wp-block-rank-math-toc-block\" id=\"rank-math-toc\"><h2>Table of Contents<\/h2><nav><ul><li><a href=\"#enabling-ping-response-on-ibm-q-radar-siem\">Enabling Ping response On IBM QRadar SIEM<\/a><ul><li><a href=\"#1-login-to-q-radar-vm\">1.

See example ping below.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>ping 192.168.43.3<\/code><\/pre>\n\n\n\n<pre class=\"wp-block-preformatted\"><code>PING 192.168.43.3 (192.168.43.3) 56(84) bytes of data.\n^C\n--- 192.168.43.3 ping statistics ---\n8 packets transmitted, 0 received, 100% packet loss, time 7069ms<\/code><\/pre>\n\n\n\n<p>Thus, to allow ICMP ping response on IBM QRadar SIEM, you have to adjust firewall rules to accept and respond to ICMP ping requests as described in the procedure below.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"1-login-to-q-radar-vm\">1.

Reload IPtables to Update the changes<\/h3>\n\n\n\n<p>Once the changes are&nbsp; made, reload the rules so that changes can take effect.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>\/opt\/qradar\/bin\/iptables_update.pl<\/code><\/pre>\n\n\n\n<pre class=\"scroll-box\"><code>\nPID=5611\n>>> Shutting down existing firewall...\n\/tmp\/iptables.5611\n\/tmp\/ip6tables.5611\n>>> Beginning update...\n Writing out rules for web access...\n>>> IPTables update complete.
